Power system studies are a set of engineering analyses used to evaluate the performance, safety, reliability, and efficiency of electrical power networks. These studies simulate how an electrical system behaves under normal and abnormal conditions—such as during faults, overloads, voltage fluctuations, or equipment failures.

By modeling your EHV, HV, or MV system using advanced software like ETAP, SKM, or PSSE, engineers can:

Identify design flaws or system weaknesses
Ensure compliance with industry standards (IEEE, NERC, OSHA)

What are EHV, HV, and MV Power Systems?
EHV (Extra High Voltage): 345kV to 800kV — used for long-distance transmission
HV (High Voltage): 69kV to 345kV — used for regional and substation-level transmission
MV (Medium Voltage): 1kV to 69kV — used in industrial, commercial, and distribution networks
Why are Power System Studies important for these voltage levels?
These studies ensure that voltage levels, current flow, and equipment response remain within safe and optimal operating conditions—preventing outages, failures, and non-compliance with standards like IEEE and NERC.
What types of studies are performed on EHV, HV, and MV systems?
Several studies are carried out to ensure the stability and reliability of power systems:

Load Flow Analysis: Determines the distribution of voltage, current, and power throughout the network under normal and peak conditions.
Short Circuit Analysis: Identifies fault levels and evaluates protection coordination to ensure the network can handle short circuit events.
Dynamic Stability Studies: Analyzes the system’s ability to withstand disturbances like faults, line outages, or generator failures.
Transient Stability Analysis: Assesses the system’s ability to return to stable operation after a disturbance.
Protection Coordination: Ensures that protective devices such as circuit breakers and relays operate correctly during faults to minimize damage.
Harmonics Analysis: Evaluates the impact of non-linear loads on the system and identifies any harmful harmonic distortion.
Why are Power System Studies important for these voltage levels?
Power system studies identify potential issues in the network such as overloading, inadequate protection schemes, and voltage instability. By conducting these studies, engineers can design systems that are more robust, select appropriate protection devices, and implement corrective measures before issues occur. This minimizes the risk of power
outages, equipment damage, and system failures.
